BURNER.

sPc'rFIcA'rIoN forming part of Letters Patent No. 631,878, dated August 29', 1899. Application filed June 9, 1899. Serial No. 719,228. (No model.)

citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, have invented certain new and useful Improvements in Burners; and I do declare the following to be a full, clear, and exact description of the invention, such as will en;` able others skilled in the art to which it appertains to .make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon,

'which form a part of this specification.

This invention relates to burners adapted to convert liquid hydrocarbon into gas and burn the latter; and the object of the in'vention is to improve the construction of such burners with a vieu'r to increase their durability and efficiency as well as to reduce the cost of their manufacture.

The invention will be fully described hereinafter, and is illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my improved burner; Fig. 2, a vertical transverse section, and Fig. 3 a plan of one plate of the burner with a spiral generating groove formed therein.

Similar reference-numerals indicate like parts in all the figures.

The bottom plate 1 of the burner is provided with a spirally-arranged groove 2, and above this plate is a sheet of asbestos 3 and another metal plate 4. The plates 1 and 4 and the asbestos sheet are firmly clamped together by a series of bolts, one of which is indicated at 5. The plate 4 is provided centrally with a recess or basin G for the reception of oil to be burned to initially heat the generating-plates. 7 indicates the top plate of the burner, and it is provided with a downwardly-extending flange S, the lower edge of which engages with the plate 4, and the plate 7 and plates 1 and 4 are secured together by a series of bolts 9. The plate 7 extends laterally beyond the fiange 8 and will preferably be of such size as to fit the lid-openin g of an ordinary cooking-stove. It is also provided with an opening 10, preferably in the center thereof, which opening may be closed when desired by a pair of hinged shutterplates 11. These shutterplates are shown in position to close the opening 10 in Fig. l and in position to leave it open in Fig. 2. Each plate 11 is pivoted at one end on a pin 12, secured in the top plate 7, and it is only necessary to swing them away from or toward each other to open or close the opening 10. rlhe plate 7 and its flange 8 form a hood for the burner inclosing the dis'- charge-pipe 17. The flange 8 is cut away to form openings 13 for the admission of air to the burner or to permit the escape of the products of combustion when the shutters are closed.

14 indicates the oil-supply pipe, which will lead from any suitable source of supply (not shown) and be provided with a valve (not shown) to regulate the supply of oil to the I burner in the usual manner. This pipe communicates with the outer end of the spiral groove, as indicated at 15. From the inner end 16 of the groove adischarge-pipe 17 leads and overhangs the basin G, into which it will discharge oil to be burned for initially heating the generator, and after the latter becomes hot enough to convert the oil in the spiral groove into vapor the vapor will be discharged from the pipe 17, and being mixed with air.

iowing in through the openings 13 will be burned. The end of the pipe 17 is preferably turned downwardly. When it is desired to let the flame escape through the opening 10, the shutter-plates will be turned out of the way. l

A burner manufactured in accordance with my invention can be produced at a very low cost, as nearly all the parts may be cast, and the parts can be assembled with a minimum of labor. I also avoid the use of generatingpipes, which are liable to crack or burn out when exposed to intense heat. The generating-passage is entirely protected by the asbestos and the vapor will be generated safely and uniformly.

Any suitable metal may be used in the construction of the burner, and the latter is adapted for use in cooking or heating stoves and also in steam-boiler or other furnaces. Any kind of hydrocarbon oil may be used, either crude or refined, and the burner will prove to be very economical in use.

Having described the invention, I claim- 1. A burner comprising a metal plate provided with a spirally-arrauged groove in its roo one end of the groove, a discharge-pipe leading from the other end of the groove to discharge into said basin, and a hood provided with openings secured to the said plates and inolosing the discharge-pipe, substantially as set forth.

2. A burner having a lower portion Aforming a generator, an oil-supply pipe leading to the generator and a discharge-pipe leading therefrom, a hood secured to the generator and inolosing the discharge-pipe, said hood having openings in-its sides and an opening for the passage of the flame in its top, and pivoted s h utter-plates to close said opening in the top of the hood, substantially as and for the purpose set forth.

In testimony whereof I ax my signature in presence of two Witnesses.
